Columnar air moving devices, systems and methods

Abstract

An air moving device includes a housing member, a rotary fan assembly, and a nozzle. The air moving device further includes a light source member mounted within the nozzle. The light source member can be placed within a flow of air moving out the end of the nozzle in a generally columnar pattern. The flow of air can be used to cool the light source member.

AI Technical Summary

Benefits of technology

The patent describes an air de-stratification device that can cool down air in a room and reduce excessive heat near the ceiling. The device also includes a light source member that can stay cool through the use of heat exchange during the process. This results in a cooler, more comfortable room.

Problems solved by technology

Air temperature stratification is particularly problematic in large spaces with high ceilings such as warehouses, gymnasiums, offices, auditoriums, hangers, commercial buildings, residences with cathedral ceilings, agricultural buildings, and other structures, and can significantly increase heating and air conditioning costs.

Structures with both low and high ceiling rooms can often have stagnant or dead air, as well, which can further lead to air temperature stratification problems.

Conventional ceiling fans are generally ineffective as an air de-stratification device in relatively high ceiling rooms because the air pushed by conventional ceiling fans is not maintained in a columnar pattern from the ceiling to the floor, and often disperses or diffuses well above the floor.

Such devices, when located away from the walls in an open space in a building, interfere with floor space use and are not aesthetically pleasing.

When confined to locations only along the walls of an open space, such devices may not effectively circulate air near the center of the open space.
